We run HPLC on every single batch before it leaves, and purity consistently hits 99.9% or better—we've had maybe two outliers in the last three years, both caught and quarantined before any shipment went out.
99.9% isn't just a number on a spec sheet because batch-to-batch consistency is what actually matters for your long-term studies, and we've logged over 200 consecutive lots with less than 0.02% variance in purity—most buyers don't ask about that until they've had a bad batch somewhere else.
Each vial comes with a COA that includes the HPLC chromatogram, residual solvent levels, and a retest date (usually 12-18 months out depending on storage), and we'll email you teh raw data file if you want it before shipment.
Not ideal for anything beyond research appliction at this purity grade, mind you, but for in vivo work or receptor binding assays it's actually tighter than what some labs use for early phase clinical materail.
A detail you might not think to check: the powder has a slight opalescence when reconstituted if stored properly at 2-8°C, and that's normal—if you ever see yellowing or clumping, that batch should be flagged and we'll replace it under our retest policy.
Lead time is roughly 5-7 business days for MOQ of 10 vials, and we hold about 500 vials in cold storage at any given time, so reorder confirmations usually ship within 48 hours of payment clearing.
The MOQ is one box, which contains 10 vials. So you're looking at 10 vials to start, but we can discuss larger volumes if you need more.
We usually ship within 3-5 business days after order confirmation and payment clearance. For bulk orders, it might take a bit longer, but we'll keep you posted.
Yes, we include a COA with every batch showing the ≥99.9% purity and other specs. If you need additional docs like an MSDS, just let us know.
We mainly stick with the 10mg/vial and 10 vials per box setup. Custom packaging for different sizes would need a larger order and some lead time—reach out to discuss specifics.
Keep it refrigerated at 2-8°C and protect it from light. That's crucial for keeping the powder stable long-term—don't freeze it or leave it out at room temp.
